the lump of dough is to be used for the letter purpose or if it divided into a number of parts, a second traveling belt Z is arranged as shown in Figs. 1, 8, and 9, which runs under a guide a.

These vapors or heated air are allowed to escape by the openingrW, if required, A l

1 he operation of theapp aratu's as a whole may be briefly sunnnarized as follows: The lumps of dough as they issue from the divider fall onto the top of the bands U through the orifiee'W and are slowly conveyed from the uppermost of these conveyors U and permitted to fall down onto the next, and so .on

.-till they reach theconveyerll", from whence they drop onto the conveyerV, by which they are .earrie .i one at a time onto the eonveyere band]; and past the knife N and guide-piece 0, where they are separated. They then fall intokthe trough A and are operated upon by the revolving rollersJ and J and by the travelin band or conveyer E, the latter 'rollingt em alongthetrough, and the ribs F in the same constantly tending to force the dough down toward'the bottom, the progression of the dough being continued to the end "*of'the trou h A, .where they aredischarged onto the s iaping device Q.
